Seed Piece & Sprouting
2-3 weeksPlant seed potatoes or pieces develop sprouts; soil is mounded over planted pieces
Ensure soil is loose and well-draining; keep consistently moist but not waterlogged; avoid planting in cold soil below 40°F
Vegetative Growth
3-4 weeksShoots emerge from soil and develop into bushy plants with leafy stems 12-18 inches tall; compound leaves are deep blue-tinted
Hill soil around plants as they grow to prevent light exposure of developing tubers; water regularly; begin fertilizing with balanced NPK or potassium-heavy formula
Flowering
2-3 weeksPlant produces blue or purple-tinged flowers; flowering indicates active tuber formation underground
Maintain consistent watering; do not disturb soil around plants; continue hilling if tubers begin showing above soil line; ensure adequate potassium
Tuber Bulking
3-4 weeksPotato tubers develop and enlarge underground with characteristic blue skin forming; plant foliage remains healthy and robust
This is the critical stage—maintain steady moisture and avoid drought stress; do not overwater which increases disease risk; reduce nitrogen fertilizer; stop hilling once tubers are fully covered
Maturity & Harvest Ready
Foliage decline over 1-2 weeksFoliage begins to yellow and decline; tubers reach full size with mature blue color; skins harden for storage
Stop watering 2-3 weeks before harvest to harden skins; reduce watering to minimum; harvest when foliage has died back; cure potatoes in cool, dark place (50-60°F) for 2 weeks before storage

Harvest Tips
Harvest when foliage has turned yellow and died back completely, typically 70-90 days after planting. Dig carefully with a fork to avoid bruising tubers. Allow soil to dry slightly before harvesting to make digging easier. For storage, cure potatoes in a cool (50-60°F), dark, humid location for 2 weeks to harden skins and heal minor cuts. Store in cool (45-50°F), dark conditions for up to 4-5 months; good ventilation prevents rot.
